[Change in the glandular bodies of the breast after hormone therapy. Observations from the radiologic viewpoint].

In the last few years we have recognized a clear change in the mammograms in women undergoing hormone replacement therapy. Not all of them reacted in the same way: 30% on 366 treated patients showed a distinct glandular hyperplasia. Some developed nodes like cysts or adenomas, others had an increase in calcification as a sign of epithelia proliferation, as verified by histological examination. The opposite effect was seen in women receiving antioestrogen therapy as a consequence of breast-conserving therapy. The problems will be illustrated.
